I haven't tried mid-grade fuel yet, which is what's recommended in the owner's manual.
 
That's odd. The Honda website lists "regular unleaded" as the correct grade of fuel for the 2005 CR-V.

Well, I just got my 6th fill-up or so.
   
This tank was completely city-driving - I did not set foot (er, tire) on a road with a speed limit above 35 the entire tank. I got 20.9 mpg (on the lowest grade of fuel), which is about the same as my VW Passat Wagon (4-cyl turbo) got, for a car with a lot more pep and space.
   
The previous tank was mostly Rocky Mt highway driving, and I got 25.1 mpg. The previous tank, which was all Rocky Mt highways (including a lot of driving through Rocky Mt National Park), I got 28 mpg.
   
Altogether, I've gotten 24.2 mpg to date. I haven't tried mid-grade fuel yet, which is what's recommended in the owner's manual.

  
READ THE MANUAL AGAIN!!!!
You probably missed the part where it says to use octane 86. Unless you are in Brazil, Eastern Europe, other developing country, or Rocky mountain region still gets 76 octane. The lowest grade sold in most of the US is 87, which is higher than recommended 86.
  
By the way, I am getting 26 mpg 95% City driving in a 2005 CR-V EX manual with 3 oz of acetone per 15 gallon tank. 24 mpg without acetone

Acetone? I guess if you do it, it wouldn't hurt the engine. Care to give some details? Thanks!

I live in Denver. Our three grades here are typically 85, 89, and 91 octane. So the lowest is lower than the manual recommends, unless I really did misread it.

I guess you are right, and I am wrong. I have been to CO and never saw 85 octane. Even CA, which has the most stringent emission requirements does not sell 85 octane.
 
Does it have to do with the lower air pressure, lower O2 concentration in the mile high city?

I really don't know why it is. I should look at the pumps again, I guess, but I've looked 2 or 3 times. I knew that 91 was the highest, so I just assumed the others would be 89 and 87, but the lowest one is 85 instead.

Costco Gas vs Chevron by northwest1

Any opinions or information out there on whether Costco regular gas is just as good as Chevron regular (or other "Top Tier" certified brand)? It seems like I get better mileage with the occasional tank of Chevron, but it is probably just my imagination. Thanks.

I can't post links, as per agreement, because the site that explains what is at work happens to have a forum board. But if you search for Honda and SUV and then search for acetone thread, you will get all the details.
 
People have been adding varyous proportions of Acetone to gasoline (not gasohol) and getting improved and not so improved fuel economy. The general ratio that works is about 2 fl oz. per 10 gallons. This is why I add 3 oz per fill. It usually takes about 12 gallons to fill, but the tank's capacity is listed at 15 gallons. I do this with Mobil brand of gasoline as I know it has no ethanol. Cheaper gas from reservations and wholesale clubs is of unknow origin. The fuel economy suffers when acetone is added to fuels containing ethanol (gasohol).
 
Last time I filled up at the Indian reservation and added 3 oz of acetone. I don't know what the fuel economy is going to be, but expect it to be worse than Mobil gas. Generally, I am getting 10% improvment in fuel economy with acetone. Some people on that board reported as much as 30% improvment.
 
I use HPLC grade acetone that I get from work. Most hardware stores sell lower quality acetone, which does not seem to have a negative effect on the fuel economy. I have not tried hardware store acetone.

tamaraster, be sure to post which model of 2005 as well. Helps to know if it is a AWD or FWD, and AT or MT.

Oh yeah, sorry about that! It's an AT AWD EX.
